How Does Hand Sanitizer Dispenser Work?

Germs are everywhere, and we need to apply caution because of what the world is going through now. Sanitizing your hands cannot be overemphasized because these germs can get into hands and items we touch during our day to day activities, which can make you sick. Cleaning hands regularly with hand sanitizer is one of the most important steps you can take to avoid being ill or spreading germs to those around you. Having clean hands is why the need to station these sanitizers in places where they can be easily spotted is very crucial. The essence of this article is to explain how hand sanitizer dispenser works.

Firstly, let's define what a hand sanitizer dispenser is. A hand sanitizer dispenser is a device used in controlling the amount of sanitizer gel for use immediately. Hand sanitizers are essential in adding the liquid for disinfecting our hands regularly. Hand sanitizer dispensers are wall-mounted or table-mounted, where it can be easily accessible to users. We place Sanitizer dispensers in the restroom, corridors, gate entrances, receptions, etc.

Hand sanitizer dispensers come in various forms. Some are automatic, where you place your hand underneath the sensor enabling the sanitizer to dispense. Hand sanitizer dispensers can also function as liquid soap dispensers, and this is because soap and sanitizer share typical viscosities.

Some others are manually operated,where you have to press or pull for the sanitizer to dispense.

Automatic soap dispensers are not just modern and fancy-looking but also very convenient. The most significant and most crucial advantage of an automated hand sanitizer or soap dispenser compared to a regular one is the fact you can use them without actually touching them. That eliminates a contact point and means fewer bacteria and a cleaner surface for a longer time. They also deliver a standardized dose of soap every time, which is pretty cool and convenient.

The overall design of our dispensers is modern and straightforward. The container clear and the rest of the body featured a combination of different color finish details. You can choose to keep the dispenser on the countertop or to have it wall-mounted. An infrared sensor detects a hand from as far as 10mm.

How It works:

When we need to have the sanitizer or wash our hands, the user’s hands are placed under the nozzle and before the sensor. The activated sensor will further activate a pump that dispenses a specific amount of sanitizer (or soap) from the nozzle. Modern sensors used in electronic faucets, electronic flush valves and electronic soap dispensers use Infrared light with wavelength in the range of 850 nm. The sensor employs an emitter and a collector. 

The emitter emits pulses of infrared light while the collector, which is positioned to face in the same direction as the emitter, "sits" dormant waiting to sense the emitted pulses. When no hands are present in front of the device, no reflection of light takes place, and therefore, no pulse is sensed. When hands are present in the path of the emitted light, a portions of the emitted infrared light is bounced back in the direction of the collector which then becomes excited by the light (in the event a photodiode is used) and generates voltage to switch the pump on. If a photo transistor is utilized, then the photo transistor, upon sensing the infrared pulse, will simply switch the pump on and dispense the sanitizer or liquid soap

Infrared sensors detect infrared energy that is emitted by one’s body heat. When hands are placed in the proximity of the sensor, the infrared energy quickly fluctuates. This fluctuation triggers the pump to activate and dispense the designated amount of soap

Advantages of Hand sanitizer dispenser:

1. Non-contact: When various individuals use the dispenser, they will leave behind a variety of bacterial colonies. These colonies will interbreed and lead to a more resistant strain of bacteria that can re-contaminate different hands and would not be completely eliminated by the anti-bacterial soap. Wider spectra or higher levels of resistance, in the colonies that are present, are due to interaction and/or complementation between the resistance genes. Without having a wide variety of individuals touching the dispenser, bacterial transmission will be eliminated and so it is for other forms of transmittable diseases.

2. Dispenses pre-measured quantity: Dispensers will only distribute a set amount of sanitizer or soap per motion activation. A predetermined amount to be dispensed can be set to a highly efficient quantity in which waste will be minimal.

3. It can work for both Soap of hand sanitizer: The mechanisms of the dispenser that work for soap may also work for other liquids: soap, hand sanitizer, lotion, laundry detergent etc. The wide range of possibilities extends the use of the dispenser to various other locations other than the bathroom.
